Preconcentration and Determination of Lead, Cadmium and Nickel From Water Samples Using a Polyethylene Glycol Dye Immobilized on Poly(Hydroxyethylmethacrylate) Microspheres
(Japan Soc Analytical Chemistry, 2006)A simple and sensitive preconcentration analysis-atomic absorption spectrometric procedure is described for the determination of lead, cadmium and nickel. The method is based upon on-line preconcentration of metal ions on ... -
Quantum Chemical Studies on The Structures of Some Heterocyclic Azo Disperse Dyes
(Arkat Usa Inc, 2008)The ground-state geometries, absorption wavelengths, oscillation strengths for a series of some novel hetarylazoindole derivatives were studied with density functional theory (DFT) and time-dependent density functional ... -
Redox Pathways of Aliskiren Based on Experimental and Computational Approach and Its Voltammetric Determination
(Soc Brasileira Quimica, 2013)Electrochemical behavior of aliskiren (ALS) was studied via experimental electrochemical methods and theoretical calculations performed at B3LYP/6-31+G (d)//AM1. Cyclic voltammetry studies were carried out based on the ... -
Release of Magnetic Nanoparticles From Cell-Encapsulating Biodegradable Nanobiomaterials
(Amer Chemical Soc, 2012)The future of tissue engineering requires development of intelligent biomaterials using nanopartides. Magnetic nanopartides (MNPs) have several applications in biology and medicine; one example is Food and Drug Administration ... -
Spectroscopic And Electrochemical Observation Of Hydrogen-Bonded Imidazole And 2-Aminoimidazole Clusters
(Slovensko Kemijsko Drustvo, 2007)The electroreductions of imidazole and 2-aminoimidazole were investigated on a Pt electrode in acetonitrile containing tetrabutylammonium tetrafluoroborate with and without the presence of HBF4. The effects of lithium and ... -
Synthesis of Some Substituted Formazans and Bis Formazans
(Asian Journal Of Chemistry, 2014)Novel 1-(p-aniinophenyl)-3-(p-substituted -phenyl)-5-phenylforrnazan compounds (2a-f) and 1,1'-(1,1'-biphenyl]-4-4'-yl)bis(3-(p- substituted pheny1)-5-plienylformazan compounds (3a-f) were synthesized by diazo coupling ... -
Synthesis of Two Novel Aroyl Thioureas and Their Use as Anion Binding Receptors
(Asian Journal Of Chemistry, 2013)New aroyl thioureas; N-nicotinoyl-N'-(4-nitrophenyl) thiourea (3a) and N-nicotinoyl-N'-(2-nitrophenyl) thiourea (3b) were synthesized and studied as anion-binding receptors. Upon adding tetrabutyl ammonium halides (fluoride, ... -

Ultrasensitive Detection And Quantification Of Acidic Disaccharides Using Capillary Electrophoresis And Quantum Dot-Based Fluorescence Resonance Energy Transfer
(Amer Chemical Soc, 2013)Rapid and highly sensitive detection of the carbohydrate components of glycoconjugates is critical for advancing glycobiology. Fluorescence (or Forster) resonance energy transfer (FRET) is commonly used in detection of ... -
Uv-Vis, Ir And Xps Analysis Of Uv Induced Changes In Pvc Composites
(Elsevier Science Bv, 1999)PVC undergoes a high degree of dehydrochlorination when exposed to energetic photons. The released HCl (acid), however, can be trapped if a suitable trapping material (base) is also enclosed within the solid matrix as a ... -
